Skötselåtgärder vid nyetablering av skyddszoner vid bäckar i södra Värmland :
Buffer zones play an important role for the water quality in our watercourses. When harvesting a forest close to a watercourse a buffer zone should be left. When it's not left, it will lead to radical changes in the environment for the water organisms. The overall purpose of this thesis was to illuminate the production- and environmental thinking when establishing new buffer zones in south of Värmland. The partials goals were to determine choice of tree species, ways of regenerate, occurrence of soil scarification and the occurrence of machine tracks in newly established buffer zones.

H?RNERVMOSSA I SANDSJ?BACKA NATURRESERVAT: Analys av h?rnervmossans invasivitet p? ljunghedens vegetationstyper
Heath star moss (Campylopus introflexus) is an alien species in Sweden and is currently classified as composing a "very high risk? of becoming invasive in the country according to SLU, and has in several parts of the world taken over large areas in a short time. The moss is characterized by its preference for disturbed and burned land, something that occurs on the heathland in the Sandsj?backa nature reserve, when burning for nature conservation purposes is carried out annually. Sandsj?backa's heathland is a valuable ecosystem and is one of the few heathlands in a favorable condition that remains in Sweden after strong reforms in modern agriculture in the last century, which led to forest succession of these cultural environments.
En utvärdering av Länsstyrelsen i Jämtlands läns uppföljning av den hotade orkidén brunkulla
Det har skett en stor förändring inom det svenska jordbruket det senaste seklet, traditionell slåtter och beteshävd har nästan upphört helt. Förändrad markanvändning orsakar habitatförlust för många växter och djur. Slåtter och betesmarkerna som hör till de artrikaste växtsamhällena i Sverige hotas av igenväxning. I denna uppsats studerar jag Länsstyrelsen i Jämtlands läns uppföljning av den starkt hotade orkidén brunkulla (Gymnadenia nigra) som är en hävdgynnad art på tillbakagång. Studien baseras på intervjuer med anställda på Länsstyrelsen i Jämtlands län samt de inventeringsdata man samlat inom uppföljningen.
Hållbar utveckling- En textanalys av miljöpolicy i lokal och nationell kontext
Sustainable development is a concept that has been interpreted in a multitude of ways in different contexts. This essay argues that the discourse of "ecological modernization" has strongly influenced the way in which the concept of ?sustainability? has been constructed in Swedish environmental policy. This interpretation of the concept of sustainability offers the possibility of combining economic growth with ecological sustainability which stands in contrast to the assumptions of Deep Ecology and Green Theory. The aim of this essay is to explore how the concept of sustainability is being formulated in environmental policy both on a national level and in the city of Malmö.Considering these issues in a specific context, this essay focuses on city planning that is as an important instrument to promote urban sustainability both on national and local levels.
Dystopi och jordens undergång : En genreanalys av dystopiska inslag i fiktiv film
This study is a research on how dystopian features are expressed within different genres. The purpose is to discuss films that contain dystopian features in relation to genre and to examine if there are shared conventions in the films that can make dystopia a film genre on its own. The theoretical base includes genre theory and Rick Altman?s semantic/syntactic approach to film genre. Five films from different genres, all produced within the time period of 2000-2010, are analyzed with a semantic/syntactic approach to genre and then discussed in relation to dystopia and prior research.
"Det är ett kluvet grattis!": en studie om unga mammors föräldraskap ur professionellas perspektiv.
The purpose of this study was to examine parenthood of young mothers from a professional point of view. The professionals work in a medium-sized city in Sweden and they represent different professions to give a broad perspective of the subject. The questions in the study were: What were the advantages of being a young mother of today and were there any problems with being a young mother, from the professionals perspective? What role did young mothers network and family play, from a professional point of view? From a professional point of view, how well did society handle young parenthood? How do the professionals handle the young mothers they met? Studies with reference to professionals' thoughts and expectations of young mothers were few, therefore the professionals were given a central position in this study. A qualitative method was chosen, for this study.
En studie av retentionen i floden Oder och dess avrinningsområden, Polen.
Nutrient enrichment is the main cause of the increasing eutrophication process in the Baltic Sea during last century. A prerequisite counteract this process the load of nutrients to the Sea must be investigated. The large contribution of nutrients to the Sea is caused by emission from the rivers within the drainage basin. For the total emission of nutrient into the Sea the retention process in the rivers has big influence. This process in the river system has been assumed as a not important part of the nutrient cycle.
Bäddodling av matpotatis :
This study investigated potato growing in beds as an alternative to conventional ridges.It was based on results from field trials on bed-grown potatoes carried out by Halland Rural Economy and Agricultural Society in 2007, studies of literature and interviews with farmers with experience of bed growing of potatoes.
Due to their shallow root system, potatoes are one of the most drought-sensitive crops. Potatoes are often grown on sandy soils with poor water-holding capacity. Factors such as total yield, tuber size distribution and quality defects are negatively affected when water becomes insufficient. Wide beds have a more flat top which leads to more uniform water infiltration. Further on, beds have lower soil surface area due to its shape, and therefore, retain water more efficient.
In the field trials, which were carried out at the Stjärnarp Estate near Halmstad, potatoes were grown in beds alongside a conventional ridge-grown crop.

Youth centres- A qualitative study of how midwives relate to the potential ethical dilemma between youths right to integrity and parents right to informationThe aim of this study was to investigate how midwives at youth centres relate to the potential ethical dilemma between parents? right to information that young people between 15-17 years share at the centre, vs. youths right to integrity. The study was based on qualitative interviews with six midwives in various youth centres in Stockholm County. We analysed our empirical material according to Blennbergers consequential ethical model and Bronfenbrenners ecological system model.
Djurparkernas tillgänglighet av information och dess innehåll: är den tillräcklig?
The purpose of zoos has changed over the decades. From being menageries where wealthy people showed their collections of exotic animals to today?s zoos where science, conservation and education has become a central part of their work. Education in zoos gives them the opportunity to spread the knowledge about ecology, biology and biodiversity to the general public. Their aim is to change the public?s attitudes towards our wildlife and raise awareness about the threats that exists against our planets biodiversity.
Inventory and evaluation of Nairobi Animal Orphanage : focusing on routines and feeding, black-backed jackal, lion and patas monkey
This BSc thesis is an introductory step to the collaboration between the Swedish zoo Skansen and Kenya Wildlife Service (KWS). It constitutes of an inventory of the Nairobi Animal Orphanage (AO), a facility that cares for injured and abandoned wildlife species in Kenya. Through the cooperation with Skansen, the KWS will improve their management of the AO. The aim of the inventory and BSc theses is to evaluate the management of black-backed jackal (Canis mesomelas), lion (Panthera leo) and patas monkey (Erythrocebus patas) regarding their biological needs. The general enclosures, routines and feeding at the AO are also evaluated since they have a great influence on the management of captive animals.
En grav är mer än bara en grav... En metodutveckling av tafonomi som redskap att förstå olika anläggningar med djur
This paper deals with a taphonomic study of contexts with osteological material of dog (C. familiaris L.) from the Mesolithic and Neolithic of Sweden and Zealand, Denmark. The general aim is to develop and test a method to try to understand the activity behind and define specific archaeological structures. My questions also regards to wether a taphonomic analysis of the material could be used to identify treatments as wrapping and contraction of the dogs, but also dismembering and other preparations of the body. The study focuses on the relation between the space of decomposition, disarti-culation of the joints, evidence of wall effect, cutmarks, weathering and signs of postdepositional arrangements.The analysis is based on contexts from the materials Hornborgasjön, Vedbæk, Skateholm I and II, Sjöholmen, Ertebølle, Bökeberg, Bredasten, Löddesborg, Bergsvägen and Röekillorna, dating from early Maglemose culture to Neolithic Battle axe culture.The analysis shows that a closer study of taphonomic processes can be used to identify different structures as graves, offerings, religious and non religious contexts or parts of animals, probably put into the ground as waste.

Zoonotic respiratory infections and great ape conservation - an emerging challenge
The conservation of great apes faces many challenges, one of which is the threat of infectious disease outbreaks. Zoonotic transmission of respiratory diseases from humans to wild great apes has recently been confirmed. Since respiratory disease is one of the major causes of
death in both gorillas and chimpanzees, this gives reason for major concern.
Little is known about the risks of disease transmission from humans to great apes in natural environments, and there is a need for systematic risk evaluation. Researchers, conservation staff and tourists spend time in very close proximity of wild great apes, sometimes during
long time periods, which poses a potential risk of disease spillover. However, the presence of researchers and tourists has been shown to decrease the risk of poaching, making the matter increasingly complex.
